Math Expressions Videos

Summaries of the research used in writing each unit as well as the mathematical background for the units. These can be a great resource to see how individual units build upon instruction from previous units and prior grade levels. At the beginning of each unit and in the middle of longer units, there is a Family Letter that explains the concepts being taught. These letters can be used as a point of reference when helping students with their homework.

An online glossary of vocabulary used within the Math Expressions program. The glossary includes audio, graphics, and animation. Online manipulatives which are similar to the hands-on activities done in class – base ten blocks, counters, number lines, etc. These can be used by students as they complete their homework. Explains the algorithms (computational procedures) that students will learn for addition, subtraction, multiplication and division.

These videos are provided by the publisher and are intended for teachers as professional development on the routines in Math Expressions and the mathematics to be taught. From a parent perspective, these videos provide insight on the ways that students are solving problems, what is being taught in the classroom, and how it is being taught.
